To all-whom it may concern:

Be 1t known that I, JAMES C. LIsroN, a

citizen rof the United States, residing atl Chatsworth, in the county of Livingston and State of Illinois, have invented certain new and useful Improvements in Marker Attachments for Corn-Planters; and l dodeclare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to makeand use the same.

This invention relates to new and useful limprovements in farming implements and more especially to marker attachments for corn planters. Y p

The mainl object of the invention resides in the provision of means for retaining the marker proper in either elevated `or inoperative position or in lowered-'or marking position.

A further object of the invention is to provide means for shifting the markerproper from elevated into lowered or marking position without necessitating that the operator move from the seat on the planter frameu A. still further object of the invention is to greatly improve and simplify the structure vshown in my patented devices Nos. 821,178- yand 881,961, patented May 22, 06 and Sept.

25, 06, respectively.

In the accompanying drawings: Figure 1 is a view in side elevation illustrating the application of. the invention to a corn planter of any approved construction, the marker proper being elevated or in an inoperative posltion. vFig. 2 is a similar view with the marker proper in lowered or in marking po- Sition. soi-ne parts broken away.

Referring to the drawing, the invention is represented or shown attached to a corn prlanter of any approved construction, -the ame of the planter consisting of side bars 1 and a rearwardly spaced cross bar 2. An adjustable supporting bar 3 which has formed in its body portion a longitudinally extending slot 4 is adjustably attached to one of the side pieces or barsof the planter frame', the forward end of the supporting. bar 3 beingbent laterally to form an outstanding ear 5 and the rear end of the bar terminating in an upwardly extending apertnredend portion 6.

Vertical clamping members 7 are arranged, one to bear against the inner face of the side piece of the frame adjacent tothaadjustable Fig. 3 is a plan view of Fig. 2 with the outer facerof said adjustable bar, said clamping members vserving to hold the supporting ar 3 in an adjusted position tothe adjacent side piece of the planter frame.

An operatin lever 8 is terminally pivoted at its lower en between the up er'ends of the clamping members 7, the bo y of the lever supporting bar 3 and the other to bear against` being preferably of forwardly curved formation and the forward terminal or inner end of 4 the same being bent laterally to form an outstanding extension 9. Said lever is also provided in the central portion 'of its body with a series of spaced apertures 10 toeither one of which may be connected the forward ends of connecting links or bars11, the rear ends of which are connected with 'an operating arm 12 keyed to the body portion 13.0f a rocker member 14, said body portion extending through the apertured end portion 6 `of the adjustable supporting bar4 3 and through :a vertically disposed apertured ear 15 formed at the upper end of a hanger member 16 attached to the cross piece 2 of the planter frame. rl`he inner end ofthe body portion of the rocker member 14 is bent rearwardly approximately at right angles to form a rearwardly extending arm 17. 'lhe hanger member 16 is formed at its lower end with two laterally spaced longitudinally alining apertured depending portions 18 designed to receive 'the forwardly bent terminal portion .19 of the marker proper, the body 20 `of which extends in a lateral direction with respect 1 to the planter frame and is provided with the usual markingl blade 21.

2Q ofthe marker proper, the purpose of which wlll be evident.

A resilient connecting element preferably A flexible connecting element 22 is arranged between the rear end of said arm 17 and the inner end of the body orward end of theoperating lever 8 which operation rocks the rocker member lain its bearings and in doing so lowers the arno 17 of the latter suiiiciently to permit the marker proper to descend until in engagement with the ground. Durin this operation the connecting links are shi 'ted from approximately ahorizontal osition to a pronounced inclined position as c early indicated in Fig. 2, while the operating arm 12 is shifted from alfor- Wardly inclined position to an approximately vertical position, under which conditions the pullA exerted on the o erating arm by the coil spring 25 is exerte at an angle approximately corresponding with the angular position of the connecting links or bars 11, retaining said links in said last mentioned position. To shift the marker proper from a lowered or marking position into an elevated position, the operator lpushes forwardly on the operating lever 8, t e spring 23 being of sufficient strength to return the marking lever, connecting links, and other coperating elements employed to shift the marker roper into operative position, after the foot ever has been suiiiciently shifted to cause the lifting pull exerted. upon the foot lever at the point of its connection with the connecting links, to more than counteract the.

25 forcel tending to retain position.

From the foregoin description taken in connection with the rawings, the construction and operation of the invention will be understood without requiring a more extended explanation.

loclaim as my invention?- 1. ln combination with 'a planter frame of apjliroximately U-shapcd form, a supporting 35.bar formed with a longitudinal slot in its body portieri adjustably attached to one side )ieee of the frame, the forward end of said liar beingr formed with an outstanding ear and the opposite end bent in a vertical plane, 40 a hanger member attached to the cross piece, of the frame, a laterally movable marker pro ier supported by the hanger men'iber, a roc 'er member comprising forwardly and rearwardly extending end portions mourited between the upper end of the hanger incinber and the rear end of the adjustable supporting bar, a flexible connection between the rearwardly extendingr arm of the rocker member and the marl-:cr proper, an operati-- ing lever pivoted above the side piece of the planter frame adjacent to the adjustable supportingr bar, horizontal connectingr linlcs arranged between thc forwardly extending end portion of the rocker member and the body of the operating lever respectively, and an oblique-ly.disposed pull springr arranged between the forwardly extending arm of the roel-:er member and the ear oll the adjustable supporting bar.

2. A marlt'er attachment for planters compri'singr a laterally movable marker mounted on the planter frame., a pull springr for normally holding the marker in an elevated or inoperative position, and connectionsunder the Controlof the operator operable to shift the lever in lowered sensei the marker into a lowered or operative posi-V tion and at the same time to relieve the'. marker of the pull normallyv exerted thereon. by said spring.

3. A marking attachment for corn planters comprising a laterally movable marker mounted in the planter frame, a rocker member com rising a rearwardly extending arm mounten at the rear of the fame, a flexible connection between the rocker member arm and marker, a ull spring arranged between the rocker mem )er and planter frame to normally hold the marker in an inoperative or elevated osition and means under the con-` trol of tie operator operable to shift the marker into a lowered or o erative position and at the same time to re ieve the same of the pull normally exerted thereon by the spring. l

4. In combination with a planter frame having a rear cross piece, ana )proximately U-shaped rearwardly extending anger member attached to the cross piece of the frame with its arms spaced longitudinally, a laterally movable marker formed with a forwardly extending ortion to extend through the arms of thellianger member, a ull spring for normally supporting the marrer in an elevated or ino erative position and means under controlp'of the oierator operable to shift the marker into a owered or o erative position against the tension of sai( spring and at the' same time to relieve the marker of the pull normally exerted thereon. by the' spring.
